I M-E'STINNETT MARION E. STINNETI', OF VICTORIA, ILLINOIS.

GRAIN-SPOUT ELEVATOR AND ADJUSTER.

Application filed July 31, 1916.

To all whom it may concern Be it known that I, MARION E. STINNETT, a citizen of the United States, residing at Victoria, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Grain-Spout Elevators and Adjusters, of which the'following is a specification, reference being had to the accompanying drawings.

This invention relates to means for elevating or lowering and adjusting elevator spouts and particularly to means for holding and adjusting the elevator spouts which are used in loading cars.

The general object of the invention is to provide a holding and adjusting device of this kind for elevator spouts which will permit the elevator to be shifted from one side door to another side door of a car without going into the car.

A furtherobject is to provide a support for grain spouts. This support is so mounted that it may be swung laterally upon a center mast or swung vertically to adjust the outer end of the support.

A further object is to provide a device of this character with a swinging telescopic boom, the extremity of the boom being provided with laterally adjustable means for supporting a grain spout.

A further object is to provide a device of this character which is very simple in construction and may be very readily operated. Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings wherein:

Figure l is a side elevation of my device;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a vertical section on the line 3'3 of Fig. 1;

Fig. 4 is a section on the line 44 of Fig. 1;

Fig. 5 is a top plan view of the plate 15;

Fig. 6 is a top plan view of the plate 17 and Fig. 7 is a top plan view of the base 10.

Referring to these drawings 10 designates a suitable base having a vertically disposed bore 11 and shown as having legs 12 whereby the base may be firmly fastened in place. Rotatably mounted upon the base 10 is a mast 13, the lower end of which is reduced in diameter as at 14 and inserted in the bore 11.

which rotates with the mast and upon the base 10, this plate being provided with a single opening or perforation 16. Resting upon the upper face of the base 10 made in Contact with the plate 15 is a plate 17. The base 10 and this plate 17 are provided with a plurality of circularly arranged bores 18 with which the perforation 16 is adapted to register. A pin 19 is adapted to be inserted through the plates 16 and 17 and into a bore 18 so as to hold the mast in a rotatably adjusted position. The mast 13 above the base is formed with a longitudinally extending slot 20 and disposed through this slot is an approximately tubular member 21 which. as illustrated in Fig. 2 is formed of relatively thin sheet metal provided with ears 22 at about its middle, through which ears passes a bolt 23 which passes through the mast and pivotally supports the member 21.

Slidingly disposed within the member 21 is a member 24 which, with the member 21, constitutes a boom as illustrated in Fig. 1. The member 21 is formed of sheet metal which is bent to only partially embrace the member 24 of the boom so as to leave a slot 25 the length of the member 21. The forward end of the member 21 is formed with a number of cars 26 to which the supporting cables are attached. These cables are joined to form a single cable 27 which extends upward to the top of the mast and there passes over a pulley 28 and then downward to a winding drum 29 having a crank 30 whereby it may be rotated. A ratchet wheel 31 is mounted in connection with the drum and is adapted to be engaged by a pawl 32. It will be obvious that by rotating the winding drum in one direction the boom will be raised and by rotating it in the other direction the boom will be lowered. For the purpose of causing the member 24 of the boom to slide in one direction through the member 21 of the boom so as to increase or decrease the length of the boom I mount upon the mast 20 a winding drum 33 provided with a crank 34 and a ratchet 35 which is engaged by a pawl 36. Carried on this winding drum is a cable 37 which extends downward and rearward and around a pulley 38. The cable is then extended to the bolt 23. The pulley 38 is mounted upon a hook or other fastening device in turn attached to the butt end of the boom member 24, the slot 25 permitting the passage of this hook 39. It will be obvious now that when the drum 33 is rotated in one direction the section 24 of the boom will be forced outward relative to the section 21 and that when the pawl 36 is lifted so as to release the drum 35 the section 24 may be telescoped into the sec tion 21.

The extremity of the section 24 is reduced in thickness as at 40 and pivotally mounted upon this reduced end is a head 41 which has lateral oscillation relative to the section 24. Mounted upon the forward end of this head is the curved spout seat 42 and disposed adjacent the middle of this seat is the hooked shaft member 48 with which this spout may be engaged.

In the practical use of my invention, the device is mounted in convenient relation to the doors of cars into which the elevator is to discharge and the spout is disposed to rest upon the seat 42. It is now obviously possible to raise or lower the free end of the boom and thereby raise or lower the spout, swing the free end of the boom laterally in a complete circle and also possible to shift the head 41 laterally to give different inclinations to the spout. The head 41 is held in laterally shifted positions by the cords or cables 44 which are attached to each end of the seat 42 and which extend upward and are adjustably engaged with a cleat 45 on the upper end of the mast. The hook '43 is intended to engage with the first joint of the elevator spout to hold the spout rigidly in place 'upon the seat. Under normal circumstances the boomcomposed of the members 21 and 24 will be inclined upward, the grain spout being inclined downward from the elevator so that the boom will slide back of its own weight when the cable 37 is unwound. It will be seen that there is no necessity of going inside the car in order to shift the spout as is the case under ordinary circumstances. The spout may be entirely adjusted from the outside and be handled easily. While I have illustrated an embodiment of my invention which I believe to be particularly practicable and which I have found effective in use, yet I do not wish to be limited to the details of the construction illustrated.

Having described my invention, what I claim is:

1. An elevator spout holding and adjusting device comprising a base, a vertically slotted mast rotatably mounted on the base, a boom made of relatively telescopic sections, one of the sections being disposed through the slot and pivoted intermediate its ends to the mast for vertical movement, an elevator support operatively carried upon the extremity of the other section, means for raising or lowering the free end of the boom andholding it in its adjusted positions, and means for shifting the spout supporting section of the boom outward relative to the pivoted section thereof.

2. An elevator spout holding anda'djust ing device comprising a base, a mast rotatably mounted thereon, a boom having rela tively telescopic sections, one of said sections being pivoted upon the mast for vertical movement, an elevator support pivotally carried upon the extremity of the other section for lateral movement in a horizontal plane, means for raising or lowering the boom and holding it in its adjusted. positions, means for shifting the spout sup porting section of the boom outward relative to the pivoted section thereof, and means for laterally shifting the elevator support and holding it in its laterally shifted positions.

8. Means for supporting adjustable elevator spouts comprising an adjustable mast vertically slotted for a portion of its length, a boom mounted for vertical movement within said slotted portion, means for raising or lowering the boom, a head pivoted upon the boom for lateral movement, means for lengthening or shortening the boom, and operating connections attached to the head and extending to the mast whereby the head may be laterally shifted and held in its shifted positions.

4. In an elevator spout supporting and holding device, a base, a mast rotatably mounted upon the base and being vertically slotted, means for holding the mast in rotatably adjusted positions relative to the base, a boom formed of telescopic sections one of said sections being disposed in said slot and pivoted to the mast for vertical movement, means for raising or lowering said boom comprising a winding drum, a cable extending from the drum to the pivoted section of the boom, and means for adjusting the other section of the boom through said pivoted section comprising a winding drum, a cable mounted thereon and having its free end operatively engaged with the mast, and a pulley on said second named section around which said cable passes.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
